Overview
Staging
Stage
Based on overall cancer staging into stages I to IV, papillary thyroid cancer has a 5-year survival rate of 100 percent for stages I and II, 93 percent for stage III and 51 percent for stage IV.[1]
Papillary thyroid cancer in patients younger than 45 years
- Stage I: In stage I papillary thyroid cancer, the tumor is any size, may be in the thyroid, or may have spread to nearby tissues and lymph nodes. Cancer has not spread to other parts of the body.
- Stage II: In stage II papillary thyroid cancer, the tumor is any size and cancer has spread from the thyroid to other parts of the body, such as the lungs or bone, and may have spread to lymph nodes.
Papillary and follicular thyroid cancer in patients 45 years and older
- Stage I: In stage I papillary thyroid cancer, cancer is found only in the thyroid and the tumoris 2 centimeters or smaller.
- Stage II: In stage II papillary thyroid cancer, cancer is only in the thyroid and the tumor is larger than 2 centimeters but not larger than 4 centimeters.
- Stage III: In stage III papillary thyroid cancer, either of the following is found:
- the tumor is larger than 4 centimeters and only in the thyroid or the tumor is any size and cancerhas spread to tissues just outside the thyroid, but not to lymph nodes; or
- the tumor is any size and cancer may have spread to tissues just outside the thyroid and has spread to lymph nodes near the trachea or the larynx (voice box)
- Stage IV: Stage IV papillary thyroid cancer is divided into stages IVA, IVB, and IVC.
- In stage IVA, either of the following is found:
- the tumor is any size and cancer has spread outside the thyroid to tissues under the skin, the trachea, the esophagus, the larynx (voice box), and/or the recurrent laryngeal nerve (a nerve with 2 branches that go to the larynx); cancer may have spread to lymph nodes near the trachea or the larynx; o
- the tumor is any size and cancer may have spread to tissues just outside the thyroid. Cancer has spread to lymph nodes on one or both sides of the neck or between the lungs.
- In stage IVB, cancer has spread to tissue in front of the spinal column or has surrounded the carotid artery or the blood vessels in the area between the lungs. Cancer may have spread to lymph nodes.
- In stage IVC, the tumor is any size and cancer has spread to other parts of the body, such as thelungs and bones, and may have spread to lymph nodes.
